Mike: I'm sorry if this has been done before, but do you view ki as being essentially bound up with micro-muscular motion and control over the body which is at a level below what is visible (or even obviously detectable) but still essentially a consequence (on a level that we don't currently understand) of gravity, Newton's laws and so on, or would you consider it to be complimentary to these ways of looking at things - 'something else'?
